I would alter this one if you think it will be the correct height for you. If you are sitting in your chair, your feet are flush on the floor, your machine should be level with your elbows bent like you are sewing. That is to releive any back or leg pain while you are sewing. I am just 4'10" since I lost 2" so I will be adjusting mine soon. I actually cut off the legs to my one machine that I have at the cottage and I cannot believe the difference. I can go a mile a minute if my boot petal would stay in place. So I am building something for that. I am tired of the stuff under the petal on the hardwood floors.
It's got to go. I would use that beautiful cabinet, have someone put a hole in it with a brace to hold the machine. Turn the machine on it's side and measure the bottom, then adjust the size so you have a lip for the machine to sit on. You can then glue some felt on the lip so it will be more sound for the machine and the machine will not rattle. Good luck!
